Make a police report: Give the officer as much information on the theft as possible: How the fraud was discovered, activity to date of fraud (in chronological order), affected accounts and losses, and any information about how the imposter got your information.

Cancel any fraudulent or compromised accounts: Immediately close and dispute any new, unauthorized accounts. The FTC has prepared an "ID theft affidavit" that is accepted by many banks and creditors at the Federal Trade Commission.

Notify Credit Bureaus: Contact one of the three credit bureaus to report the theft. When contacted, the credit bureaus will put a "fraud alert" on your credit report to prevent any further fraudulent accounts from being opened. As soon as one of the credit bureaus places a fraud alert, the other two bureaus are automatically notified to do the same and you should receive a free credit report from all three bureaus.

Review your credit reports carefully: Look for changes in old accounts and look for newly opened accounts. Check your name, address and Social Security number for any changes. Have the credit agencies remove all information in your credit report that results from the theft. Order new credit reports every three months until your situation is cleared up.
